ALPS touchpad not seen by 2.6.11 kernels

ALPS touchpad not seen by 2.6.11 kernels

[Johan Braennlund]

Hi. I've had trouble with my ALPS touchpad on my Acer Aspire, ever
since ALPS support was merged into the kernel. I've tried various
kernels from 2.6.11-rc3 to -rc5 (including some -mm kernels) and none
of them detect the pad. After sprinkling some printk's in the mouse
drivers, it seems like psmouse_connect in psmouse-base.c is never even
called. 

On the other hand, using earlier kernels (such as 2.6.9) with the
kernel patch from Peter Osterlund's driver package works fine. In that
case, I get lines like this in syslog:

kernel: alps.c: E6 report: 00 00 64
kernel: alps.c: E7 report: 73 02 14
kernel: alps.c: E6 report: 00 00 64
kernel: alps.c: E7 report: 73 02 14
kernel: alps.c: Status: 15 01 0a
kernel: ALPS Touchpad (Glidepoint) detected
kernel: input: AlpsPS/2 ALPS TouchPad on isa0060/serio4

With the newer kernels, there's nothing ALPS-related in the log. Any
pointers on what to look for would be appreciated. My kernel config is
at http://nullinfinity.org/config-2.6.11-rc5

Thanks,

Johan

Hi,

Does i8042 detect presence of an AUX port (check dmesg)? If not try
booting with i8042.noacpi kernel boot option.

No.

Yes, that helped - everything's working now. Thank you.

Could you please send me contents of your DSDT
(cat /proc/acpi/dsdt > dsdt.hex)

Thanks!

After applying your patch, I can confirm that the kernel detects the
touchpad without the i8042.noacpi option. Thanks!

I have had the same problem and the solution worked for me as well.

Where should I put the DSDT?

Please reply to my e-mail, as I am no linux-kernel subscriber.

Just e-mail it to me - I suspect your PS/2 port has a wierd ID assigned
to it, one that i8042 driver does not expect.

Thanks for DSDT! Could you please try the follwing patch?

Andrew, if this works I'd like to see it in 2.6.11...
Vojtech, I will send you patch for PNP shortly after.
